EST1 — Brassica oleracea

Summary

BoEST1, encoded by gene BOLC102_C04P014960.1 on cabbage chromosome 4, is an ATP-binding cassette (ABC) transporter of the ABCC subfamily, possessing multiple transmembrane domains and AAA+ ATPase domains. The gene is associated with transmembrane transport of abscisic acid glucose ester, arsenite, xenobiotics, aluminum ions, UDP-glucose, phosphate, and sulfate, and with detoxification of aluminum and arsenic. It is linked to leaf development, and its product localizes to the tonoplast, vacuole, plasma membrane, and plasmodesmata. BoEST1 has been connected to traits including stamen number and length, auxin and brassinosteroid sensitivity, cell elongation, organ identity, seed and root morphology, and plant growth and development. It is also associated with arsenic resistance, cadmium tolerance, salt tolerance, anthocyanin accumulation, chlorophyll degradation, and auxin transport.
